HOT-WATER-PIPE ARRANGEMENT FOR HEATING PURPOSES.

SPECIFICATION forming part of Letters Patent No- 358,636, dated March 1,1887.

Application filed Apri 16, 1886.

To aZZ whom it may concern:

Be it known that 1, WILLIAM ANTONEY WHITE, of Staatsburg, in the countyofDutchess and State of New York, have invented new and usefulImprovements in Hot-WVatenPipe Arrangements for Heating Purposes, ofwhich the following is a full, clear, and exact description.

This invention, while applicable to various heating purposes by the flowor circulation of hot water through pipes, is more particularly designedfor heating hot-houses, green-houses, and for other like structures orpurposes. Ordinarily, where pipes arranged to run in eourses,the oneabove the other,and connected at the terminal of the combined courseswith a furnace or boiler for passing hot water there from and returningit thereto, are used to establish a circulation of the hot water throughthe several courses of a tier of pipes, itis cus tomary to make the flowfrom the boiler along the upper course of the coil or tier of pipes andto return it to the boiler along the lower course of the coil or tier.This produces very unequal heating, retards the circulation by reason ofthe tendency which hot water has to rise and not to descend, and iswasteful of fuel.

My invention consists in certain novel eonstructions and combinations ofparts whereby U these objections are removed and special advantagessecured, substantially as hereinafter described, and pointed out in theclaims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 represents an elevation, partly in vertical section, on line yy, Fig. 2, of a hotwater boiler or furnace with a series ofhotwater-circulating coils and other parts or devices in illustration ofmy invention, the coil of pipes nearest to the eye being omitted; andFig. 2 is a sectional plan of the same upon the line as w in Fig. l.

A is a many-sided water-heating furnace fitted internally with separatewater heating coils B B B B on its several or any number of its sides;but no claim is here made to the special construction of the furnace,the same being the subject of a separate application Serial No. 199,082.(No model.)

(Serial No. 193,873, filed March 3, 1886) for patent by me, and it mightbe otherwise constructed.

O G C C indicate separate hot-water-circulating pipes or coils,ot'similar construction, and each separately connected with the boileror separate water-heating coils B B B 13* therein, so as to secure anindependent action or use for each of the water-circulating coils C C O"0*, that run in diiferent directions relatively to each other, for thepurpose of producing a more extended distribution of the heat. Each coil0 O G" 0 consists of any number of straight lengths of pipe arranged oneabove the other and communicating alternately in reverse directions attheir opposite ends to form acontinuous serpentine pipe. The flow fromthe coil of pipes B 13 B B", located in the furnace, is taken from aboveand connected along the lower length, 0, of the circulatingcoils C C OO, and the hot water travels in an upward direction along the upperlength or lengths of pipe and passing along the uppermost length, 0, isfinally returned to the. lower end of the coils B B B 13* by a leg ordownward bend, 0 Thus the circulation through the coils O O C O isalways a rising one, which, being in accordance with the natural courseof heated liquids, secures a perfeet and rapid circulation and gives abottom heat in the coil,that is lacking when the return flow is throughthe lower length of pipe in said coil.

The feed of water for circulating purposes is made to each coil 0 C C Oand coil or separate watereompartment B B B B' of the boiler by aseparate pipe, (Z, from a tank, D, or other source, and each coil 0 G G0* is separately fitted at its highest point with a rising pipe, 6, forthe escape of air from the coil and,its connections,or for the overflowof any water from an excess of supply in the coil.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The combination, with a furnace and a series of independent waterheating coils therein, of separate hot-Water-circulating coils arrangedabove said heating-coils and proj ecting in different directions'andhaving their lower lengths connected with the upper pordirections andhaving their lower lengths, 0,
